Maybe, the pins on your footprint of the layout is swapped? In this case, your device should have a mechanical shutter in front of the receptacles, so that users should plug to just one receptacle at a time.

How is it possible that i detect something like a pen drive being inserted. Sorry, I’ve forgot to write on this modification in above post. Which option do you take, a direct connection, or b Connection over analog switches?

These cables are not so popular on the market, yet. Just replace the jumper blocks with analog switches. Important information This site uses cookies to store information on your computer. By continuing to use our site, you consent to our cookies.

For b Over analog switches option, such a sliding door is not required. Kindly let me know if what i am trying is right. Your Host circuit is almost similar to Olimex one. Aha surely, It’s PNP.

Is there any other method to detect the plug-in of USB Stick? Kindly give your suggession. And are there any changes that are supposed to be made while the controller is used a end device. After detecting the USB stick, software should turn on the both trasistors before transferring data and after completion of data transfer software should turn off the both trasistors right?

Isn’t that the obvious way to go for something that needs to be both a Host and a Device?! The code is as follows. This site uses cookies to store information on your computer.

Both receptacles are always exposed to users. The USB Device is enumerated fine for above code.

Detecting Pen Drive Insertion on LPC1768

If i am detecing the insertion in interrupt mode then even after detection, there will be variations on the line while data transfer and this can cause unpredictable interrupts. When the door switch detects role change, firmware disable current role, and it calls stack initialization for each role, host or device. This is for end device.

And USB Device circuit is at following link http: For a Direct connection method, a sliding door is necessary so that users don’t plug in to both receptacles at a time. But the emitter and the collector are swapped on the schematic.

The schematic I have send of USB device is working fine. You may want to attach these accessories to your product set for user’s convenience. Products Download Events Support Videos.

Scu fine similar discussion on Microchip USB forum http: When you take b over analog switches, the Olimex circuits around the receptacles are applied as is.
